10.ビクトリア褐炭の高温高圧下における加溶媒分解

抄録

Solvolysis of Loy Yang coal was studied in supercritical methanol. The conversion increased with the reaction temperature from 33% at 300℃ to 73% at 400℃, when 0.2g of brown coal was reacted in 70ml methanol. The holding time at 400℃ did not influence the conversion of the 0.2g brown coal, showing the occurring reaction was so rapid. When the mass of brown coal was increased up to 20g vs 70ml methanol, the conversion decreased to 45%. However, comparison with a previous work on methanolysis of subbituminous coal, brown coal was found to have high reactivity toward supercritical methanol.
